Wormholes Untangle a Black Hole Paradox
An anonymous reader writes: Like initials carved in a tree, ER = EPR, as the new idea is known, is a shorthand that joins two ideas proposed by Einstein in 1935. One involved the paradox implied by what he called "spooky action at a distance" between quantum particles (the EPR paradox, named for its authors, Einstein, Boris Podolsky and Nathan Rosen). The other showed how two black holes could be connected through far reaches of space through "wormholes" (ER, for Einstein-Rosen bridges). At the time that Einstein put forth these ideas — and for most of the eight decades since — they were thought to be entirely unrelated.
But if ER = EPR is correct, the ideas aren't disconnected — they're two manifestations of the same thing. And this underlying connectedness would form the foundation of all space-time. Quantum entanglement — the action at a distance that so troubled Einstein — could be creating the "spatial connectivity" that "sews space together," according to Leonard Susskind, a physicist at Stanford University and one of the idea's main architects. Without these connections, all of space would "atomize," according to Juan Maldacena, a physicist at the Institute for Advanced Study in Princeton, N.J., who developed the idea together with Susskind. "In other words, the solid and reliable structure of space-time is due to the ghostly features of entanglement," he said. What's more, ER = EPR has the potential to address how gravity fits together with quantum mechanics.

Mind = blown
Please to beggings for a version around which I can wrap my tiny brain? Something related to automobiles perhaps?
If video games influenced behavior the Pac Man generation would be eating pills and running away from their problems.
That's all I had to say.
...in fiction, basic discoveries of this magnitude promptly lead to anti-gravity, flying cars, space travel, and replicators.
In real life, some PhDs are pleased with themselves and now understand why we exist and aren't a cloud of random particles - but I *still* don't get a damn jet pack.
Oh, well: the announced today that they have asthma figured out at last and can probably cure it soon. I don't have asthma, but I'm glad we also got a practical discovery.
Finally proof of the existance of the Ether. Now onto the subether. R.I.P E.E. Smith. ;)
There, solved it for you. Where's my grant money?
If quantum entanglement is a manifestation of 'communications' through a wormhole, then can we create an entangled particle pair, drag one far, far away and start poking it (with some signal). Then, we should be able to observe it's paired partner and extract that signal.
Even if this doesn't give us faster-than-light communications, it has uses. Imagine a submarine with one of a pair of particles in a transmitter. Wiggle (bounce, or whatever) that particle and watch its partner on land. You now have a comm link (possibly at a high speed) from or to an environment that isn't affected by the r.f. propagation problem. Also, untappable optical (or whatever) links. Because there is no physical medium between the endpoints for the NSA to tap.

"Because we are not employing at entry level, offshoring will kill our industry stone dead."
Imagine a chicken's butt. picture it. Okay hang onto that thought because we'll come back to that later.
There's a house made of rubber with a lot of rooms. While all the guests including the butler are gathered in the living room, the guests hear the sound of the master of the house being murdered in his bedroom which is at the end of a distant series of hallways. They also notice that at that moment the butler is missing, but a moment later he's back. It's too far from the dining room to the bedroom for the Butler to have walked there and walks back, so he's not a suspect. But we have two mysteries
1) how did the butler vanish and re-appear. Very suscipicious. could he teleport?
2) how did they hear the scream of the master in his distant bedroom.
The second fact seems to clear the butler since no one wants to believe in teleportation.
Then they discover the house is U-shaped and there's a secret passage directly connecting the bedroom to the living room. The spooky actions and effects at a distance are explained by a wormhole. Also it's the secret passage way that holds the rubber house in a U-shape.
Now remember that chicken butt? I thought so. See if you can get it out of your mind.
Some drink at the fountain of knowledge. Others just gargle.
illuminati!
So if you drop one of an entangled pair of particles in a black hole, they stay entangled through a wormhole?
Wish I had mod points left. But could you please explain this with butlers, chickens and rubber houses?
All I'm seeing is "some guy posted a blog entry about a three-year-old paper". Surely it must have been on Slashdot before, though I can't actually find it with Google.
Here’s the heart of their argument: If a black hole’s event horizon is a smooth, seemingly ordinary place, as relativity predicts (the authors call this the “no drama” condition), the particles coming out of the black hole must be entangled with particles falling into the black hole. Yet for information not to be lost, the particles coming out of the black hole must also be entangled with particles that left long ago and are now scattered about in a fog of Hawking radiation. That’s one too many kinds of entanglements, the AMPS authors realized. One of them would have to go.

This just validates my pet hypothesis. Finally science is catching up to stuff I figured out years ago. Also something something spirit God the universe emerges from consciousness and not the other way around. Now, allow me to read to you briefly from my manifest...
Its always looked like a Magicians Trick.. or a Shell game.
They were always one and the same
Just as E=MC^2 which is what they're alluding too
It also explains the Speed of Light, and Speed of Time, Expansion and so many other things
I sometimes wonder why people puzzled over this for so long.. or is it a joke.. and I'm the only one that didn't get it?
This is, without doubt, the most intelligent and informative Slashdot conversation I have ever read. HAND.
If ER = EPR then dividing both sides by ER leaves P = 1. That wasn't as hard as it first looked.
Of course if P=1, then P = NP too!
> the "spatial connectivity" that "sews space together," ...

And the large structure of the universe, bubbles/voids/walls, is evidence left behind wherever an intelligent species discovered a way of fiddling with that connectivity -- intending superluminal travel. That eventually punches a lot of holes in that connectivity, and their local group of galaxies falls out of space leaving a bubble.
Like it says on the bag: Tear along perforation ...
... now all it needs is a light side and a dark side.

It's always the ones who know nothing about relativity who keep saying it's a bad theory. It's an amazing coincidence of idiocy and the colossal hubris to think that you are literally smarter than Einstein. Could there be a more extreme example of the Dunning-Kruger effect?
Why can't we just assume that since there are 9 dimensions, the connection between quantum entangled particles travels through a higher dimension. Doesn't that solve everything more tidily? In fact, I don't remember if NASA's experiment with entanglement on the space station disproved faster than light communication (I think the rocket with the experiment onboard blew up) but it would even explain that if it were true. It travels faster than light because it doesn't, it shortcuts through a higher dimension and rejoins normal space.
Science has not proved and cannot prove that Quantum Entanglement is a real phenomenon, because it cannot be measured: as soon as one measures the particles, the entanglement is destroyed.
Furthermore, science has not proved that quantum entanglement is particles linked or particles created symmetrically. For all we know, entangled particles may be born in symmetrical state and not be linked at all.
Thirdly, we haven't even proved that a single photon is a wave. We have shown that a stream of light particles acts as a wave, through the double slit experiment, but not an individual photon.
We also have not proved that the interference pattern we are seeing in the double slit experiment is not due to spacetime ripples that create certain paths for photons to travel to instead of photons being waves.
In the double slit experiment, if the slits are turned sideways or become circular or rectangular, the interference pattern on the projector changes accordingly.
However, if the slits are enlarged, the interference pattern ceases.
This means that what actually happens is that there is a collision of photons with the slits, when the slits are small enough. When the slits are enlarged, there is no collision, and therefore no interference pattern.
When we put a detector between the electron/photon gun and the slits, the electron/photon emitted by the gun is absorbed by the detector and reemmited from the other side of the detector in a straight line, because the detector and the slits form a straight geodesic line, and thus the emitted electron/photon goes straight through the slit and does not collide with the slit walls.
I bet that if the detector is placed right where the opening hole of the electron/photon gun is, and the slits are moved slowly away from the detector, the interference pattern will reemerge, showing that there is no wave function to collapse, and thus proving that QM is the best error mankind ever did.
If there IS a connection as suggested (the equation), then maybe our difficulty in comprehension is due to our 3D limitations of space/time.
There was a famous book (citation needed, but I do remember it being mentioned in Kasner's 'Mathematics and the imagination') about people living in flat land. Their bank was a simple square drawn on paper. We could rob their bank by picking up the object from above. In THEIR site, the object would simple disappear into nothing.
Imagine if the same thing was done to us and items apparently disappeared or reappeared, as if by magic.
If we are bound by the rules and models we currently use, then we'll be as mystified and confused as the 2D people.
'No', I don't understand it and am keen to read someone else's explanation that would be good for a bunch of 15 year old high school students - I always believe that people who really understand something can reduce the whole affair into simple terms, rather than use technical language that obscures.
